Description

Technical Field

[0001] The invention belongs to the technical field of pressure vessel processing, in particular to a pressure vessel cutting and welding integrated machine. Background Art

[0002] A pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure. In the processing of pressure vessels, cutting and welding of pressure vessels are two key links, which respectively involve the cutting and connection of materials. The existing pressure vessel cutting and welding technologies have, to a certain extent, achieved development in the direction of integration. These devices have achieved the integration of cutting and welding functions through special design and configuration. Such all-in-one machines are usually equipped with a multi-functional laser head or plasma cutting head, which can switch different functional modules according to different processing requirements.

[0003] A patent application with publication number CN118527868A discloses a pressure vessel cutting and welding machine, including a mounting plate, on which two circular rings one and two circular rings two are slidably connected, a clamping mechanism is arranged between circular ring one and circular ring two, a long plate is fixed between two fixed plates, and a cylinder is fixed on the long plate. The cutting and welding machine can clean dust and impurities at the welding point of the pressure vessel, and can also filter the smoke generated during the welding process.

[0004] There are still some problems in the actual application of the above scheme. Although the above-mentioned cutting and welding machine can filter the smoke generated by welding during the welding process and remove some of the harmful gases generated during welding, after long-term use, the aging of the filter material may affect its filtering effect, thereby allowing harmful gases to continue to invade the workers.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1: Figures 1 to 12As shown, a pressure vessel cutting and welding machine according to an embodiment of the present invention comprises an operating table 1, a base platform 2 is provided at one end of the operating table 1, a clamping structure 3 is provided at the upper end of the base platform 2, the clamping structure 3 comprises two clamping rings 34, the two clamping rings 34 are slidably connected to the upper end of the base platform 2, a placement structure 4 is provided between the two clamping rings 34, the placement structure 4 comprises two placement plates 44, a cutting and welding structure 5 is provided on the side wall of the base platform 2, the cutting and welding structure 5 comprises a fixing frame 51, the fixing frame 51 is provided on the side wall of the base platform 2, an operating head 53 is provided at the upper end of the fixing frame 51, and an adjustment structure 6 is provided on the surface of the operating head 53; the adjustment structure 6 comprises: an outer wrapping frame 601, an outer wrapping frame 601 It is arranged at the upper end of the fixed frame 51, and the operating head 53 slides inside the outer wrapping frame 601; the slide groove 605, the slide groove 605 is opened on the inner wall of the outer wrapping frame 601; the inner wrapping frame 603, the inner wrapping frame 603 is slidably connected to the inner wall of the slide groove 605; the adjusting frame 602, the adjusting frame 602 is arranged at one end of the inner wrapping frame 603, and the upper end of the adjusting frame 602 is rotatably connected with the first grinding roller 609 and the second grinding roller 613; the exhaust plate 606, the exhaust plate 606 is slidably connected to the inside of the adjusting frame 602; the slag trough 608, the slag trough 608 is opened at the opening of the adjusting frame 602; the exhaust port 619, the exhaust port 619 is opened at one end of the adjusting frame 602 away from the slag trough 608.

[0023] Specifically, the scheme provides a pressure vessel cutting and welding integrated machine, which is mainly used for cutting and welding the pressure tank 7. When working, the pressure tank 7 is first placed on the surface of the placement plate 44, and then the clamping ring 34 is started. One of the two clamping rings 34 will move toward the other clamping ring 34 and contact the pressure tank 7, and finally the pressure tank 7 is abutted between the two clamping rings 34 to be fixed, and then the outer wrapping frame 601 is moved to the welding position attached to the pressure tank 7, and then the inner wrapping frame 603 is started, so that the inner wrapping frame 603 slides in the slide groove 605 on the inner wall of the outer wrapping frame 601, and finally the outer wall of the pressure tank 7 is welded. Wrap it up so that the part to be welded is sealed, and then start the operating head 53, which is an arc welding cutting head, which can realize the dual functions of welding and cutting. During operation, the current passes through the air gap between the operating head 53 and the pressure tank 7, generating ionization, forming a stable arc and melting the metal, and then the metal solidifies to form a weld, thus realizing the welding of the part of the pressure tank 7. At this time, start the rotation of the clamping ring 34, which will drive the pressure tank 7 to rotate, so that the pressure tank 7 can be welded in all directions. During the welding process, start the first grinding roller 609 and the second grinding roller 613 to rotate. When the seam rotates to contact with the first grinding roller 609 and the second grinding roller 613, the first grinding roller 609 and the second grinding roller 613 can grind and clean the welding slag produced by welding. Since the operation is performed inside the inner packaging frame 603, it is possible to avoid the splashing welding slag from injuring people. The grinding welding slag will also fall out of the slag trough 608, thereby ensuring that the welding slag will not splash into the interior of the adjusting frame 602. During the welding process of the pressure tank 7, the exhaust plate 606 is started, and the exhaust plate 606 will slide on the inner wall of the adjusting frame 602. Since the side wall of the exhaust plate 606 is in contact with the inner wall of the adjusting frame 602, the exhaust plate During the movement, 606 will draw the harmful gas generated by welding into the interior of the adjusting frame 602 and discharge it from the exhaust port 619, and a pipe can be set at the lower end of the exhaust port 619 to guide the flow of the harmful gas. After one extraction, the remaining harmful gas can also be discharged from the slag trough 608 during the resetting of the exhaust plate 606, thereby exhausting the harmful gas for a second time. By setting the inner wrapping frame 603 and the outer wrapping frame 601, the harmful gas can be preserved during the welding process, and the adjusting frame 602 can also continuously extract the harmful gas and effectively transfer the harmful gas, thereby purifying the working environment.

[0024] like Figures 1 to 8As shown, a sliding rail 21 is provided at the upper end of the base platform 2, and the clamping structure 3 also includes: a sliding plate 31, which is slidably connected to the surface of the sliding rail 21; a fixing plate 32, which is arranged at the upper end of the sliding plate 31; a connecting ring 33, one of the two connecting rings 33 is arranged on the surface of the operating table 1, and the other connecting ring 33 is arranged on the surface of the fixing plate 32, and two clamping rings 34 are respectively arranged on the surfaces of the two connecting rings 33; the placement structure 4 also includes: a sliding sheet 41, which is slidably connected to the surface of the sliding rail 21, and a placement plate 44 is arranged The upper end of the sliding sheet 41; the cutting and welding structure 5 also includes: a fixed frame 51, the fixed frame 51 is fixedly connected to the side wall of the base platform 2; a steering arm 52, a plurality of steering arms 52 are arranged at the upper end of the fixed frame 51, and the steering arm 52 is connected to the outer wrapping frame 601; the adjustment structure 6 also includes: a slider 604, the slider 604 is arranged on the surface of the inner wrapping frame 603, and the slider 604 slides on the inner wall of the slide groove 605; a connecting rod 607, the connecting rod 607 is slidably connected to the inside of the adjustment frame 602, and the connecting rod 607 is arranged at one end of the exhaust sheet 606.

[0025] Specifically, during operation, the pressure tank 7 is first placed on the surface of the placement plate 44, and then the sliding plate 31 is started. The sliding plate 31 will drive the fixing plate 32 to move toward the direction of the pressure tank 7, and then the clamping ring 34 located on the surface of the fixing plate 32 will first contact the pressure tank 7, and push the pressure tank 7 to move toward the clamping ring 34 on the side of the operating table 1, and finally fix the pressure tank 7, and then start the steering arm 52 to drive the outer wrapping frame 601 to move to the welding position attached to the pressure tank 7. In the subsequent welding process, the connecting rod 607 is started, and the vacuum plate 606 can be driven to move through the connecting rod 607 to realize the transfer of harmful gases.

[0026] like Figures 1 to 12 As shown, two connecting frames 610 are provided at the upper end of the adjustment frame 602, and a sliding bar 616 is provided at one end of the two connecting frames 610 close to each other. The surface of one of the two sliding bars 616 is slidably connected to the first gear 614, and the surface of the other sliding bar 616 is slidably connected to the second gear 615, and the first gear 614 is close to the first grinding roller 609, and the second gear 615 is close to the second grinding roller 613. The surfaces of the first grinding roller 609 and the second grinding roller 613 are both covered with connecting tracks 618, and the other end of the connecting track 618 is covered on the arc surface of the connecting frame 610, and a tooth plate 612 is provided at the upper end of the connecting rod 607, and the first gear 614 and the second gear 615 are meshed with the tooth plate 612 during operation.

[0027] Specifically, when the first grinding roller 609 is started for grinding, the second gear 615 near one end of the second grinding roller 613 is started first, so that the second gear 615 slides on the surface of the sliding bar 616, so that the second gear 615 is not meshed with the tooth plate 612, and then the first grinding roller 609 will drive the first gear 614 to rotate through the connecting track 618. During the rotation, the first gear 614 will mesh with the tooth plate 612, so that the tooth plate 612 drives the exhaust plate 606 to move through the connecting rod 607, thereby removing harmful gases. After the gas extraction is completed and discharged from the exhaust port 619, the first gear 614 and the second gear 615 are started, so that the first gear 614 slides on the surface of the sliding bar 616, so that the first gear 614 is not engaged with the tooth plate 612, and the second gear 615 moves to engage with the tooth plate 612, and the second grinding roller 613 is started at this time. Since the second grinding roller 613 rotates in opposite directions to the first grinding roller 609, the second grinding roller 613 will drive the exhaust plate 606 to move in the opposite direction, thereby realizing reset for subsequent cycle operations.

[0028] like Fig. 9 As shown, a reset rubber block 611 is provided on the upper surface of the adjustment frame 602 , and the reset rubber block 611 is in contact with the connecting rod 607 .

[0029] Specifically, since the connecting rod 607 is connected to the tooth plate 612, and the tooth plate 612 is arranged on the outside of the adjusting frame 602, by setting a reset rubber block 611 on the upper surface of the adjusting frame 602, the reset rubber block 611 will crack a small gap when it contacts the connecting rod 607, so that the connecting rod 607 can move. When the reset rubber block 611 does not contact the connecting rod 607, the reset rubber block 611 on the upper surface of the adjusting frame 602 will abut against it, thereby closing the adjusting frame 602 and preventing harmful gas from leaking sideways.

[0030] Embodiment 2: Fig.11 As shown, compared with the first embodiment, another implementation of the present invention is that a clamping ball 617 is provided at one end of the second gear 615 , and both the first gear 614 and the second gear 615 are clamped with the clamping ball 617 .

[0031] Specifically, since the first gear 614 and the second gear 615 both slide on the surface of the sliding bar 616, when they slide to engage with the tooth plate 612, the first gear 614 and the second gear 615 will engage with the engaging ball 617, thereby ensuring that they will not loosen during the engagement process.

[0032] like Fig.12As shown, the connection frame 610 slides on the upper surface of the adjustment frame 602 , and in the initial state, the connection frame 610 is located at an end away from the slag dropping groove 608 .

[0033] Specifically, by setting the connection frame 610 to slide on the surface of the adjustment frame 602, the position can be adjusted according to the pressure tanks 7 of different sizes, so that the welding slag grinding can be performed more accurately.

[0034] like Figures 1 to 4 As shown, a telescopic cylinder 42 is provided at the upper end of the sliding sheet 41 , a telescopic rod 43 is provided at the upper end of the telescopic cylinder 42 , and the telescopic rod 43 is connected to a placement plate 44 .

[0035] Specifically, by setting up the telescopic cylinder 42, the height of the pressure tank 7 located on the surface of the placement plate 44 can be adjusted at will, so that when dealing with pressure tanks 7 of different sizes, it can be ensured that the pressure tank 7 and the two clamping rings 34 are on the same horizontal line to facilitate subsequent clamping and fixing work.

[0036] like Figures 1 to 4 As shown, two trays 45 are provided on the upper surface of the placement plate 44 , and the upper surfaces of the trays 45 are opened in an arc shape, and the thickness of the trays 45 is relatively large.

[0037] Specifically, by setting a tray 45 on the upper surface of the placement plate 44, the pressure tank 7 can be placed on the surface of the tray 45. Since the upper surface of the tray 45 is arc-shaped and has a large thickness, the tray 45 and the pressure tank 7 can fit better, thereby making the placement of the pressure tank 7 more stable.

[0038] like Figure 5 As shown, a plurality of universal balls 36 are disposed inside one of the two clamping rings 34 .

[0039] Specifically, by setting a universal ball 36, the pressure tank 7 is fixed in the two clamping rings 34, and during welding, since one of the two clamping rings 34 needs to drive the pressure tank 7 to rotate, a universal ball 36 is set inside the clamping ring 34 that does not rotate. The universal ball 36 will contact the pressure tank 7, which can reduce the friction between the clamping ring 34 and the pressure tank 7 and increase the service life of the pressure tank 7.

[0040] like Figure 5 As shown, a rubber pad 35 is provided at one end of the connecting ring 33 away from the clamping ring 34 .

[0041] Specifically, since the clamping ring 34 fixes the pressure tank 7 by squeezing, the rubber pad 35 can be provided to buffer the squeezing force, thereby reducing the damage to all parts caused by the squeezing force.

[0042] Working principle: During operation, first place the pressure tank 7 on the surface of the tray 45, then start the telescopic cylinder 42, adjust the pressure tank 7 to be on the same horizontal line with the two clamping rings 34, then start the sliding plate 31, the sliding plate 31 will drive the fixing plate 32 to move toward the direction of the pressure tank 7, then the clamping ring 34 located on the surface of the fixing plate 32 will first contact with the pressure tank 7, and push the pressure tank 7 to move toward the clamping ring 34 on the side of the operating table 1, and finally fix the pressure tank 7, then start the steering arm 52, and the outer wrapping frame 601 can be driven to move to the welding position attached to the pressure tank 7, and the inner wrapping frame 603 is started, so that the inner wrapping frame 603 is in the slide groove 605 on the inner wall of the outer wrapping frame 601 The pressure tank 7 is welded by the second grinding roller 614, and the second gear 615 is driven by the second grinding roller 616 to move along the second grinding roller 617. The second gear 615 is driven by the second grinding roller 616 to move along the second grinding roller 617. The second gear 615 is driven by the second grinding roller 616 to move along the second grinding roller 617. The second gear 615 is driven by the second grinding roller 616 to move along the second grinding roller 617. The second gear 615 is driven by the second grinding roller 616 to move along the second grinding roller 617. The surface slides so that the second gear 615 does not mesh with the tooth plate 612, and then the first grinding roller 609 is started to grind and clean the welding slag. Since this operation is performed inside the inner wrapping frame 603, it can avoid the splashing welding slag from hurting people. The welding slag after grinding will also fall out of the slag trough 608, thereby ensuring that the welding slag will not splash into the interior of the adjusting frame 602. The first grinding roller 609 will also drive the first gear 614 to rotate through the connecting track 618. During the rotation, the first gear 614 will mesh with the tooth plate 612, so that the tooth plate 612 drives the exhaust plate 606 to move through the connecting rod 607. Since the side wall of the exhaust plate 606 is in contact with the inner wall of the adjusting frame 602 Therefore, the exhaust plate 606 will draw the harmful gas generated by welding into the interior of the adjustment frame 602 during the movement, and discharge it from the exhaust port 619. After the gas extraction is completed and discharged from the exhaust port 619, the first gear 614 and the second gear 615 are started, so that the first gear 614 slides on the surface of the sliding bar 616, so that the first gear 614 is not engaged with the tooth plate 612, and the second gear 615 moves to engage with the tooth plate 612, and the second grinding roller 613 is started at this time. Since the second grinding roller 613 rotates in opposite directions to the first grinding roller 609, the second grinding roller 613 will drive the exhaust plate 606 to move in the opposite direction, thereby achieving reset for subsequent cycle operations.
